The image file does work out of the box.

The normal activation process for that image no longer works though. (has not been fixed for a few month now)
Then there is a bug with the gpg server command in their install script they recommend to run, which then fails. There are work arounds for this problem as well, but no one is fixing it.
The read-only bug is something they also don't seem to be fixing.
Maybe they'll fix all those problems soon and prove us wrong

They also use an outdated dump1090 version, so if you want a more current version, i still recommend

Power problems are actually quite common with the RPi.
What the problem with your "failure to resolve" was, i have no idea though.
If you are using an USB WiFi adapter, maybe that wasn't happy with the lower voltage as well
